As cyberattacks grow more sophisticated, banks increasingly turn to advanced authentication to protect customer data. Widespread biometrics adoption represents not only a top banking trend for 2018 but also a long-term market shift. A report from Global Market Insights predicts that use of the technology within financial services will grow by 22 percent between 2017 and 2024.

That projection reflects the view that passwords — which customers often repeat or simplify in the name of convenience — are no longer a sufficient security barrier.

“If you think about all the breaches and everything going on in the world, passwords need to go away,” Michelle Moore, head of digital banking at Bank of America, told The Charlotte Observer. “No. 1, people forget them. No. 2, they’re not safe.”

Instead, banks see physical and behavioral biometrics as a stronger and more user-friendly means of verifying an individual’s identity. Many have already begun pilots or full-scale efforts to adopt the advanced authentication methods.

Fingerprint Recognition Reigns Supreme

Enabling mobile application sign-on with a simple swipe, fingerprint scanning wears the crown as the most widely leveraged biometric in the industry. The technology first made waves in mobile banking after Apple introduced Touch ID in 2013, and institutions have since found that customers are willing to make the switch.

That adoption rate could be linked to the technology’s perceived effectiveness. A 2017 EyeVerify survey found that 86 percent of banking customers familiar with biometrics had used fingerprint recognition at least once within the last year, while 87 percent of respondents considered the method to be the most secure form of authentication.

Iris and Facial Scanning Gain Steam

Although Global Market Insights data shows that fingerprint technology will see the most growth by 2024, the report indicates that other authentication technologies will follow suit. The iris recognition market, in particular, will see double-digit growth between 2017 and 2024.

Facial recognition, also on track for growth across industries, is seeing a boost from the launch of Apple’s Face ID system. Banking customers with an iPhone X can so far use Face ID to log in to mobile apps from the likes of U.S. Bank and Citibank, but other institutions will probably explore the technology, given that iPhone X doesn’t support Touch ID.

Biometrics Support Multilayered Security, Customer Experiences

With so many options available for biometric identification, banks could choose to mimic multifactor authentication and require users to provide a combination of biometric identifiers to reduce the potential of fraud even further.

For now, though, banks such as Wells Fargo offer multiple options to make the process more flexible for customers. “One biometric doesn’t fit every situation,” Steve Ellis, head of Wells Fargo’s innovation group, said in an interview with Tearsheet. “For example, if I’m driving in my car and I want to talk to the bank, I’m not going to authenticate with my fingerprint, but maybe my voice could be the password.”

With that kind of innovative, customer-focused thinking taking place at institutions across the country, it’s clear mobile banking is entering a new era of security and convenience.
